Unix timestamp converter

Paste a timestamp, or pick a date and time.

A Unix timestamp is the number of seconds since 00:00:00 UTC on January 1, 1970, not counting leap seconds. Computers use it because one number means the same moment everywhere.

Seconds or milliseconds?

Ten digits is seconds (1798761600). Thirteen digits is milliseconds (1798761600000), which JavaScript and many APIs use.

Time zones

A timestamp has no time zone; it is the same moment everywhere. The converter shows it in UTC and in your device’s local time.
